JSR233 sampler with Java to work with Selenium Webdriver (javax.script.ScriptException: In file: inline evaluation)

Question

Trying to run Selenium Webdriver script in Jmeter using JSR233 sampler. The script works fine in Eclipse IDE, however in Jmeter facing below error.

ERROR o.a.j.p.j.s.JSR223Sampler: Problem in JSR223 script JSR223 Sampler, 
message: javax.script.ScriptException: In file: inline evaluation of:

Below is the script trying to execute:

    import java.util.HashMap;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.chrome.ChromeOptions;
    import org.openqa.selenium.remote.CapabilityType;
    import org.openqa.selenium.remote.DesiredCapabilities;
    import org.openqa.selenium.By;
    import org.openqa.selenium.support.ui.WebDriverWait;
    import org.openqa.selenium;
    System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
    String downloadFilepath = "D:/MyDeskDownload";
    HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
   // chromePrefs.put("profile.default_content_settings.popups", 0);
   // chromePrefs.put("download.default_directory", downloadFilepath);
   // chromePrefs.put("safebrowsing.enabled", "true"); 
    ChromeOptions options1 = new ChromeOptions();
    options1.setExperimentalOption("prefs", chromePrefs);
    DesiredCapabilities cap = DesiredCapabilities.chrome();
    cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    cap.setCapability(ChromeOptions.CAPABILITY, options1);
    WebDriver driver = new ChromeDriver(cap);
    driver.setJavaScriptEnabled(true);
    driver.get("http://google.com/");

I have gone through below references to get above script:

• Running Selenium scripts with JMeter

• How to use WDS variable in BSF or JSR233 (JMeter)

We could achieve launching a browser and performing actions with Selenium Webdriver config sampler with JavaScript however since we are unable to set capabilities with WDS, we are trying to achieve the same in JSR233.

Answer 1

From stacktrace it looks you are using JSR223 with Beanshell or Java (which will be beanshell).

Since it's Beanshell, it doesn't understands generics (diamond operator) so this line:

HashMap<String, Object> chromePrefs = new HashMap<String, Object>();

So you need to just switch the language to Groovy to fix the problem:

Answer 2

Beanshell doesn't support the diamond operator to if you really want to continue wiht Beanshell - change this line:

HashMap<String, Object> chromePrefs = new HashMap<String, Object>();

to this one

HashMap chromePrefs = new HashMap();

Be aware that starting from JMeter version 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting, the reasons are in:

• Groovy supports all the modern Java language features
• Groovy provides a lot of enhancements over standard Java SDK
• Groovy provides much better performance than Beanshell

So consider migrating to Groovy, my expectation is that no changes will be required (you might need rewriting lambdas into closures if any, however the overhead will be minimal)
